Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to a fixture for mold processing. Background Technology

[0002] A mold-making fixture is a device specifically designed to fix and position a mold during the mold-making process. Its main function is to ensure the stability and precise positioning of the mold during processing in order to meet the requirements of high-precision machining.

[0003] Existing mold processing fixture designs do not take into account the flexible adjustment of mold blank thickness, resulting in the fixture being unable to adapt when clamping thicker or thinner mold blanks. This can easily lead to local protrusions due to uneven clamping force or incorrect clamping angle, which in turn damages the fixture. Long-term use may cause fixture deformation, loose clamping, or even affect processing accuracy.

[0004] Therefore, existing mold processing fixture designs do not consider the flexible adjustment of mold blank thickness, resulting in the fixture being unable to adapt when clamping thicker or thinner mold blanks. This can easily lead to localized protrusions due to uneven clamping force or incorrect clamping angles, causing damage to the fixture. Long-term use may lead to fixture deformation, unstable clamping, and even affect processing accuracy. To address this, a mold processing fixture can be designed with added adjustment functions, such as using a sliding clamping mechanism with scale adjustment or an elastic clamping structure. This allows for rapid adjustment of clamping force and position according to the thickness of the mold blank, ensuring uniform distribution of clamping force and avoiding damage to the fixture from localized protrusions. The improved fixture can effectively extend its service life while improving processing stability and accuracy, providing more efficient and reliable support for mold processing. Utility Model Content

[0006] The technical solution of this utility model is as follows: a fixture for mold processing, including a worktable; and an adjustment component. The adjustment component is provided at the bottom of the worktable. The adjustment component includes a movable groove, a moving groove, a lead screw, a motor, a lifting frame, a knob, a threaded rod, a lifting block, a moving frame, a motor, a bidirectional screw, and a clamping block. Movable grooves are provided on the front and rear sides of the top of the worktable, and a moving groove is provided at the bottom of the worktable. A lead screw is rotatably connected inside the moving groove. A motor is connected to the left end of the worktable, and the output end of the motor is connected to the lead screw. A lifting frame is threadedly connected to the outer end of the lead screw. The lifting frame is slidably connected to the moving groove. A knob is rotatably connected to the bottom of the lifting frame. The top of the knob extends into the lifting frame and is connected to a threaded rod. The threaded rod is drive-connected to the lifting frame. A lifting block is threadedly connected to the outer end of the threaded rod.

Clamping blocks are connected to the front and rear sides of the outer end of the bidirectional screw. The clamping blocks are slidably connected to the moving frame.

[0007] Preferably, by setting an adjustment component, starting the motor, the motor drives the lead screw to rotate, the lead screw rotates and causes the lifting frame to slide in the moving groove, adjusting the jig to move left and right, rotating the knob, the knob drives the threaded rod to rotate in the lifting frame, thereby causing the lifting block to move the moving frame vertically, the moving frame to move the clamping block vertically, and then adjusting according to the thickness of the mold blank, starting the motor, the motor drives the bidirectional screw to rotate, thereby causing the clamping block to slide in the moving frame to clamp the mold blank, thereby improving the flexibility of the device, solving the problem that the existing mold processing jig design does not consider the flexible adjustment of the mold blank thickness, resulting in the jig being unable to adapt when clamping thicker or thinner mold blanks, and easily causing local protrusion due to uneven clamping force or incorrect clamping angle, which in turn damages the jig, and may lead to jig deformation, loose clamping, or even affect the processing accuracy after long-term use.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up the adjustment component and starting the motor, the motor drives the lead screw to rotate, which in turn causes the lifting frame to slide within the moving slot. Adjusting the clamping fixture moves left and right, and rotating the knob causes the threaded rod to rotate within the lifting frame, thereby causing the lifting block to move the moving frame vertically. The movement of the moving frame then causes the clamping block to move vertically, thus adjusting according to the thickness of the mold blank. Starting the motor drives the bidirectional screw to rotate, which in turn causes the clamping block to slide within the moving frame, clamping the mold blank. This improves the flexibility of the device and solves the problem that existing mold processing fixture designs do not consider the flexible adjustment of mold blank thickness. This results in the fixture being unable to adapt when clamping thicker or thinner mold blanks, and is prone to local protrusion due to uneven clamping force or incorrect clamping angle, which can damage the fixture. Long-term use may lead to fixture deformation, insecure clamping, and even affect processing accuracy. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to Figure 1- Figure 4This utility model provides an embodiment: a fixture for mold processing, including a worktable 1; it also includes an adjustment component. The adjustment component is provided at the bottom of the worktable 1. The adjustment component includes a movable groove 21, a sliding groove 22, a lead screw 23, a motor 24, a lifting frame 25, a knob 26, a threaded rod 27, a lifting block 28, a sliding frame 29, a motor 210, a bidirectional screw 211, and a clamping block 212. The movable groove 21 is provided on the front and rear sides of the top of the worktable 1, and the sliding groove 22 is provided at the bottom of the worktable 1. The lead screw 23 is rotatably connected inside the sliding groove 22. The motor 24 is connected to the left end of the worktable 1. The output end of the motor 24 is connected to the lead screw 23. The lifting frame 25 is threadedly connected to the outer end of the lead screw 23. The lifting frame 25 is slidably connected to the sliding groove 22. The knob 26 is rotatably connected to the bottom of the lifting frame 25. The top of the knob 26 extends into the lifting frame 25 and is connected to the threaded rod 27. The threaded rod 27 is connected to the lifting frame 25. In the transmission connection, the outer end of the threaded rod 27 is threadedly connected to a lifting block 28. The right end of the lifting block 28 is connected to a moving frame 29. The front end of the moving frame 29 is connected to a motor 210. The output end of the motor 210 extends into the moving frame 29 and is connected to a bidirectional screw 211. The bidirectional screw 211 is transmissionally connected to the moving frame 29. Clamping blocks are connected to the front and rear sides of the outer end of the bidirectional screw 211.

[0024] 212. Clamping block 212 is slidably connected to moving frame 29. By setting an adjustment component, motor 24 is started, motor 24 drives lead screw 23 to rotate, lead screw 23 rotates and drives lifting frame 25 to slide in moving groove 22, adjusting the clamp to move left and right. Rotating knob 26 drives threaded rod 27 to rotate in lifting frame 25, thereby causing lifting block 28 to drive moving frame 29 to move vertically. Moving frame 29 moves clamping block 212 to move vertically, and then adjusts according to mold blank thickness. Motor 210 is started, motor 210 drives bidirectional screw 211 to rotate, thereby driving clamping block 212 in moving frame 29. The internal sliding mechanism clamps the mold blank, thereby improving the flexibility of the device. This solves the problem that existing mold processing fixtures do not consider the flexible adjustment of mold blank thickness. As a result, when clamping thicker or thinner mold blanks, the fixtures cannot be adapted and are prone to local protrusion due to uneven clamping force or incorrect clamping angle, which can damage the fixtures. Long-term use may lead to fixture deformation, unstable clamping, and even affect the processing accuracy.

[0025] Please refer to Figure 1- Figure 4In this embodiment, a positioning plate 31 is connected to the top of the workbench 1. The top of the positioning plate 31 has multiple positioning holes 32 at equal intervals. The positioning plate 31 and the positioning holes 32 can adjust the position of the mold blank according to the external processing equipment, which facilitates the processing of the mold blank and improves flexibility. A placement plate 33 is movably connected to the top of the positioning plate 31. The top left and right sides of the placement plate 33 have mounting grooves 34. The placement plate 33 can be positioned in conjunction with the positioning holes 32 to place the mold blank on the placement plate 33, thereby facilitating the adjustment of the position of the mold blank according to the position of the external processing equipment. There are two mounting screws 35 movably connected inside the mounting grooves 34. The mounting screws 35 are threaded to the positioning holes 32. By passing through the mounting grooves 34 and connecting to the positioning holes 32, the placement plate 33 is fixed on the positioning plate 31.

[0026] Please see Figures 2-4 In this embodiment, support rods 36 are connected to the bottom left and right sides of the workbench 1. There are four support rods 36. The support plate is used to support the workbench 1. Two support rods 36 are connected to a support frame 37 near the center of the workbench 1. The support frame 37 is U-shaped. The support frame 37 increases the force-bearing area and makes the device more stable. There are two support frames 37. The bottom of the two support frames 37 is connected to a rubber plate 38. The rubber plate 38 is used to increase the friction with the ground and improve the stability of the device.

[0027] During operation, the mounting screw 35 passes through the mounting slot 34 and connects to the positioning hole 32, thereby fixing the placement plate 33 onto the positioning plate 31. The motor 24 is started, driving the lead screw 23 to rotate. The rotation of the lead screw 23 causes the lifting frame 25 to slide within the moving slot 22. The adjustment fixture moves left and right by rotating the knob.

[0028] 26. Knob 26 drives threaded rod 27 to rotate within lifting frame 25, thereby causing lifting block 28 to drive moving frame 29 to move vertically. Moving frame 29 drives clamping block 212 to move vertically, and then adjusts according to the thickness of mold blank. Start motor 210, motor 210 drives bidirectional screw 211 to rotate, thereby causing clamping block 212 to slide within moving frame 29 to clamp the mold blank. Support frame 37 increases the force-bearing area, making the device more stable. Rubber plate 38 is used to increase friction with the ground and improve the stability of the device.

[0029] Through the above steps, by setting the adjustment component, starting the motor 24, the motor 24 drives the lead screw 23 to rotate, the lead screw 23 rotates and drives the lifting frame 25 to slide in the moving groove 22, adjusting the jig to move left and right, rotating the knob 26, the knob 26 drives the threaded rod 27 to rotate in the lifting frame 25, thereby causing the lifting block 28 to drive the moving frame 29 to move vertically, the moving frame 29 moves and drives the clamping block 212 to move vertically, and then adjust according to the thickness of the mold blank, starting the motor 210, the motor 210 drives the bidirectional screw 211 to rotate, thereby causing the clamping block 212 to slide in the moving frame 29 to clamp the mold blank, thereby improving the flexibility of the device, solving the problem that the existing mold processing jig design does not consider the flexible adjustment of the mold blank thickness, resulting in the jig being unable to adapt when clamping thicker or thinner mold blanks, and easily causing local protrusion due to uneven clamping force or incorrect clamping angle, which in turn damages the jig, and long-term use may lead to jig deformation, insecure clamping, and even affect the processing accuracy.
